Wash the meat, pat dry and cut into pieces. Clean and wash the carrots and mushrooms. Cut carrots into cubes, mushrooms into slices. Peel onions and cut them into fine pieces.
Heat the oil. Fry the meat and onion in it and season. Stir in carrots and mushrooms and sauté. Add the stock and peas and simmer for about 5 minutes.
Mix the flour and cream together until smooth. Tie the ragout with it. Season to taste with salt, pepper and lemon juice (possibly fondor and onion salt). Pour into an ovenproof dish. Spread the pasta on top. Sprinkle the grated cheese evenly over the top.
Bake in a preheated oven (fan oven: 200 ° C) for 10-15 minutes.
